Coitus interruptus, also known as the withdrawal or pull-out method, is a method of birth control in which a man, during sexual intercourse, withdraws his penis from a woman's vagina prior to orgasm (and ejaculation) and then directs his ejaculate (semen) away from the vagina in an effort to avoid insemination. This method of contraception, widely used for at least two millennia, is still in use today. Coitus interruptus does not protect against sexually transmitted infections. The advantage of coitus interruptus is that it can be used by people who have objections to or do not have access to other forms of contraception. Some people prefer it so that they can avoid possible adverse effects of hormonal contraceptives. Other reasons for the popularity of this method are that it has no direct monetary cost, requires no artificial devices, has no physical side effects, can be practised without a prescription or medical consultation.
